Description

Connector with a locking member

Technical Field

The present application relates to a connector, and more particularly, to a connector having a terminal module.

Background

U.S. patent No. US9,935,385 (chinese counterpart application publication No. 107706675 a) discloses a receptacle connector. The patent discloses that a front portion of a dielectric carrier of the receptacle connector may face in opposite directions and may engage a housing. The front portion of one or both of the dielectric carriers may include one or more securing features for securing a contact assembly to the housing. The fixing part may interact with a corresponding fixing part of the housing to fix the contact assembly to the housing. For example, the securing features may be any combination of clips, latches, snaps, protrusions, openings, or other types of securing features. In the embodiment shown in this patent, the securing feature is a ramp-shaped catch for interacting with the corresponding latch on the housing.

The housing includes a securing member that interacts with the securing member of the contact assembly to retain the contact assembly in a contact assembly cavity. In the embodiment shown in this patent, the securing member is a latch for engaging a catch that defines the securing member; however, in alternative embodiments of this patent, other types of such securing members may be provided. The fixing parts are arranged on the two side walls; however, in an alternative embodiment of the patent, only one side wall may have the securing feature. In other alternative embodiments of this patent, the end wall may include a securing member.

In this patent, the fixing member is provided on a side wall of the housing. In order to form the fixing member, it is inevitable to modify the side wall of the housing so that the side wall has a relatively thin thickness and is easily deformed by an external force. Thus, the holding force of the housing holding the dielectric carrier in the housing is relatively weak.

The above "background" description merely provides background, and no admission is made that the above "background" description discloses subject matter of the present application and does not constitute background of the present application, and any description of the above "background" should not be taken as an admission that the present application is of any sort.

Referring to fig. 1 to 3, the connector 1 includes a first terminal module 2A, a second terminal module 2B and a housing 3, wherein the embodiment includes two other terminal modules as a set of terminal modules in addition to the first terminal module 2A and the second terminal module 2B; however, for the sake of simplicity of explanation, only the first terminal module 2A and the second terminal module 2B will be exemplified below.

The housing 3 is elongated extending in the longitudinal direction Xl-X2. The housing 3 has a mounting surface 34, a mating surface 35, a slot 350 disposed on the mating surface 35 and extending in the length direction Xl-X2, a first side wall 30 and a second side wall 31 extending in the length direction Xl-X2 and defining the slot 350, and a first end wall 32 and a second end wall 33 enclosing the slot 350 together with the first side wall 30 and the second side wall 31 and extending in the width direction Y1-Y2. The first end wall 32 connects the first side wall 30 and the second side wall 31, and the second end wall 33 connects the first side wall 30 and the second side wall 31.

The first terminal module 2A is mounted to the housing 3 in the mounting direction Z1. The first terminal module 2A includes a first insulating body 20A and a plurality of first terminals 22A fixed to the first insulating body 20A. In some embodiments, the first terminal 22A is disposed on the first insulating body 20A, for example, by injection molding (insert molding).

The second terminal module 2B includes a second insulative housing 20B and a plurality of second terminals 22B fixed to the second insulative housing 20B. In some embodiments, the second terminal 22B is disposed on the second insulative body 20B, such as by injection molding.

Each of the first and

second terminals

22A, 22B includes a tail portion 24 on the mounting face 34 (shown in fig. 2) and a resilient contact portion 26 in the slot 350 (shown in fig. 7).

Fig. 4 is a bottom perspective view of the first terminal module 2A of the connector 1 in fig. 2 separated from a first receiving groove 36A of a housing 3 of the connector 1, wherein the second terminal module 2B of the connector 1, a set of terminal modules and the two-plate locking member 4 of the connector 1 are omitted. Fig. 5 is a bottom perspective view of the second terminal module 2B of the connector 1 of fig. 4 separated from a second receiving groove 36B of the housing 3 of the connector 1, wherein the first terminal module 2A of the connector 1 is omitted. Fig. 6 is a partially enlarged bottom plan view of the connector 1 in relation to fig. 2. Fig. 7 is a cross-sectional plan view of the connector 1 of fig. 2 along a section line in the width direction Y1-Y2. Referring to fig. 4 to 7, the housing 3 further includes an accommodating space 36 communicating with the slot 350, and a partition wall 6 dividing the accommodating space 36 into a first accommodating groove 36A and a second accommodating groove 36B, wherein the partition wall 6 connects the first end wall 32 and the second end wall 33.

The first terminal module 2A is mounted to the first receiving groove 36A between the partition wall 6 and the first side wall 30 in the mounting direction Z1 and is latched to the partition wall 6 of the housing 3, as shown in fig. 4.

The second terminal module is mounted to the second receiving slot 36B between the partition wall 6 and the second side wall 31 in the mounting direction Z1 and is locked to the partition wall 6 of the housing 3, as shown in fig. 5.

In the present application, the first terminal module 2A and the second terminal module 2B are latched to the partition wall 6 located inside the housing 3 to hold the first terminal module 2A and the second terminal module 2B in the housing 3, rather than being latched to the first side wall 30 and/or the second side wall 31 of the housing 3. Since it is not necessary to form a member that interacts with the first terminal module 2A and the second terminal module 2B on the first side wall 30 and/or the second side wall 31 of the housing 3, the first side wall 30 and/or the second side wall 31 of the housing 3 is relatively thick and is not easily deformed by an external force. Therefore, the holding force of the housing 3 for holding the first terminal module 2A and the second terminal module 2B in the housing 3 is relatively strong.

The partition wall 6 includes a first side 61 (shown in fig. 5) facing the first side wall 30, and a second side 62 (shown in fig. 4) facing the second side wall 31. In one embodiment, the partition wall 6 is parallel to the first sidewall 30 and the second sidewall 31. In other embodiments, the partition wall 6 is partially parallel to the first side wall 30 and the second side wall 31.

The partition wall 6 further includes a first elastic portion 68A and a second elastic portion 68B, and a body portion 69 of the partition wall 6 is disposed beside each of the first elastic portion 68A and the second elastic portion 68B. The body portion 69 on the first elastic portion 68A side is connected to the body portion 69 on the second elastic portion 68B side. The body portion 69 on the other side of the first elastic portion 68A and the body portion 69 on the other side of the second elastic portion 68B are connected to the second end wall 33 and the first end wall 32, respectively.

The first elastic portion 68A is provided with a first engaging groove 654A on the first side surface 61 of the partition wall 6, and the first engaging groove 654A is closer to the second end wall 33 than to the first end wall 32. The first insulating body 20A includes a first protrusion 200A for engaging with the first engaging slot 654A on the first side 61 of the partition wall 6. Accordingly, the first terminal module 2A is latched to the partition wall 6 located inside the housing 3. In addition, the first elastic portion 68A further includes an elastic piece 65A protruding from the body portion 69 of the partition wall 6 in the insertion direction Z2, and a slit 66A provided beside both sides of the elastic piece 65A. In detail, a top surface 656A of the elastic piece 65A protrudes from a top surface 690 of the body portion 69 of the partition wall 6. Accordingly, the elasticity of the elastic piece 65A is relatively preferable. However, the first elastic portion 68A of the present application is not limited thereto. In one embodiment, the elastic piece 65A of the first elastic portion 68A does not protrude from the body portion 69 of the partition wall 6 in the insertion direction Z2, but includes slits 66A disposed beside both sides of the elastic piece 65A. In another embodiment, the first elastic portion 68A includes the elastic piece 65A protruding from the body portion 69 of the partition wall 6 in the insertion direction Z2, but does not include the slit 66A.

During the process of inserting the first terminal module 2A into the first receiving groove 36A, the elastic piece 65A is pushed by the first protrusion 200A of the first terminal module 2A and elastically expands toward the second side wall 31 of the housing 3. When the first protrusion 200A of the first terminal module 2A moves into the first locking groove 654A of the first elastic portion 68A, the elastic piece 65A elastically restores toward the first sidewall 30 of the housing 3. Accordingly, when the first terminal module 2A is received in the first receiving slot 36A, the first protrusion 200A of the first terminal module 2A is locked with the first locking slot 654A.

In addition, a first concave portion 202A is further provided at the first insulating body 20A of the first terminal module 2A facing the second elastic portion 68B. It is assumed that the first terminal module 2A is already accommodated in the first accommodation cavity 36A before the second terminal module 2B is inserted into the second accommodation cavity 36B. As described above, when the second terminal module 2B is inserted into the second receiving groove 36B, the elastic piece 65B of the second elastic portion 68B is elastically outwardly expanded toward the first side wall 30 of the housing 3. At this time, the first recess 202A accommodates the elastic piece 65B of the second elastic portion 68B.

The second elastic portion 68B is provided with a second engaging groove 654B on the second side 62 of the partition wall 6, the second engaging groove 654B being closer to the first end wall 32 than to the second end wall 33. The second housing 20B includes a second protrusion 200B that engages with a second slot 654B on the second side 62 of the partition wall 6, as shown in fig. 7. Accordingly, the second terminal module 2B is latched to the partition wall 6 located inside the housing 3. In addition, the second elastic portion 68B includes an elastic piece 65B protruding from the body portion 69 of the partition wall 6 in the insertion direction Z2, and a slit 66B provided beside both sides of the elastic piece 65B. In detail, a top surface 656B of the elastic piece 65B protrudes from the top surface 690 of the body portion 69 of the partition wall 6. Accordingly, the elasticity of the elastic piece 65B is relatively preferable. However, the second elastic portion 68B of the present application is not limited thereto. In one embodiment, the elastic piece 65B of the second elastic portion 68B does not protrude from the body portion 69 of the partition wall 6 in the insertion direction Z2, but includes slits 66B disposed beside both sides of the elastic piece 65B. In another embodiment, the second elastic portion 68B includes the elastic piece 65B protruding from the body portion 69 of the partition wall 6 in the insertion direction Z2, but does not include the slit 66B. In the present application, various embodiments of the first elastic portion 68A and various embodiments of the second elastic portion 68B can be arranged and combined to form various different embodiments.

During the process of inserting the second terminal module 2B into the second receiving slot 36B, the elastic piece 65B is pushed by the second protrusion 200B of the second terminal module 2B to be elastically outwardly expanded toward the first side wall 30 of the housing 3. When the second protrusion 200B of the second terminal module 2B moves into the second locking groove 654B of the second elastic portion 68B, the elastic piece 65B elastically restores toward the second sidewall 31 of the housing 3. Accordingly, when the second terminal module 2B is received in the second receiving slot 36B, the second protrusion 200B of the second terminal module 2B is locked to the second locking slot 654B.

In addition, a second concave portion 202B is further disposed at the second insulating body 20B of the second terminal module 2B facing the first elastic portion 68A. It is assumed that the second terminal module 2B is already accommodated in the second accommodation cavity 36B when the first terminal module 2A is inserted into the first accommodation cavity 36A. As described above, when the first terminal module 2A is inserted into the first receiving groove 36A, the elastic piece 65A of the first elastic portion 68A is elastically outwardly expanded toward the second side wall 31 of the housing 3. At this time, the second recess 202B accommodates the elastic piece 65A of the first elastic portion 68A.

Referring back to fig. 2, 3 and 7, the connector 1 further includes at least one plate locking member 4. The board lock 4 is configured to be inserted in the insertion direction Z2 and to penetrate a lock hole 55 of the housing 3. The present embodiment includes a two-plate latch 4. Each of the plate latches 4 includes a fixing portion 40 fixed in the locking hole 55 of the housing 3, a tail portion 42 penetrating the locking hole 55 of the housing 3, a body portion 41 extending from the fixing portion 40 to the tail portion 42 in the insertion direction Z2, and a guide portion 46 located on opposite sides of the fixing portion 40 from the body portion 41 and providing a guide to the insertion slot 350. In the present embodiment, an interference protrusion 44 is disposed on each of two sides of the fixing portion 40 to be in interference with the inner wall surface of the locking hole 55. In the present embodiment, the guide portion 46 has a slope, and extends toward the outer side of the housing 3 along the mounting direction Z1. Accordingly, the board lock 4 is configured to guide the end edge of a board edge when the board edge is inserted into the slot 350 in the insertion direction Z2.

When the connector 1 is electrically and mechanically connected to a circuit board (not shown), the tail portions 42 of the board lock members 4 protrude from the housing 3 and are inserted into a fixing hole (not shown) of the circuit board to fix the connector 1 to the circuit board, and the tail portions 24 of the first terminals 22A and the second terminals 22B may be mounted on the circuit board by Surface Mounting Technology (SMT), or by through hole soldering (through hole) technology, press fitting (press fit) technology, or the like.

Fig. 8 is a schematic sectional plan view of the connector 1 related to fig. 7, in which only the housing 3 of the connector 1 is shown. Referring to fig. 8, the housing 3 further includes a first coupling rib 53 and a second coupling rib 54. The first coupling rib 53 is configured to connect the partition wall 6 and the first sidewall 30, and the second coupling rib 54 is configured to connect the partition wall 6 and the second sidewall 31; furthermore, referring back to fig. 4, both ends of the partition wall 6 are connected to the first end wall 32 and the second end wall 33, respectively. Thus, the partition wall 6 can be relatively firmly fixed in the housing 3. However, the present application is not limited thereto. In some embodiments, the first and

second coupling ribs

53 and 54 couple the partition wall 6 to the first and

second side walls

30 and 31, respectively, but both ends of the partition wall 6 are not coupled to the first and

second end walls

32 and 33. In some embodiments, the housing 3 does not include the first coupling rib 53 and the second coupling rib 54, and both ends of the partition wall 6 are connected to the first end wall 32 and the second end wall 33, respectively.

The housing 3 further includes a plurality of partition ribs 67 provided on the body portion 69 of the partition 6, and a plurality of end wall ribs 51 provided on the first end wall 32 and the second end wall 33 (see fig. 4, 5, and 8). The partition ribs 67 and the end wall ribs 51 are interference-fixed with each of the wall surfaces of the first insulating body 20A of the first terminal module 2A and the wall surfaces of the second insulating body 20B of the second terminal module 2B to preferably hold the first terminal module 2A and the second terminal module 2B in the housing 3.
